Buying Guide: Key Considerations For Refurbished Dual Fuel Generators
- Fuel flexibility: Dual-fuel models offer gasoline and propane options. Consider local fuel availability and the expected duration of outages to choose the right mix.
- Power needs: Determine your essential load. If you only need lights and small electronics, compact units suffice. For home backup, prioritize higher running watts and peak watts.
- Start mechanism: Electric start is convenient, but ensure you can manually start the unit if the battery fails. Remote starts add comfort for frequent use during outages.
- Noise level: Inverter generators typically run quieter than traditional open-frame models. If you live in a neighbor-heavy area, noise can be a deciding factor.
- Run time and fuel capacity: Longer runtimes reduce refueling frequency. Compare tank sizes and EPA/CO safety features when evaluating models.
- Outlets and transfer switches: Look for transfer switch readiness and a mix of outlets (120V, 240V, RV, etc.) to cover home and appliance needs.
- CO safety features: Models with CO detectors or shutdown features improve safety in occupied spaces.
FAQ
- What does “dual fuel” mean in practical terms? It means the generator can run on gasoline or propane, giving you flexibility based on fuel availability and price.
- Are refurbished generators reliable? Refurbished units can offer solid value when inspected and tested; check return policies and warranty terms before purchasing.
- Which wattage is best for a modest home backup? A unit in the 3000–5000 running watts range typically covers essential loads like lights, fridge, and modem.
- Is propane a good long-term fuel option? Propane stores well and doesn’t degrade like gasoline, but fuel availability and conversion efficiency should be considered.
- Do I need a transfer switch with a large generator? Yes, for safe, code-compliant connection to home circuits during outages. Some units are transfer-switch ready by design.
- Can I use these generators indoors? No. Even with CO sensors, operating a generator indoors or in a garage is dangerous and not recommended.
